The objective of the Pathway Ranking for In-place Sediment Management (PRISM) was to provide an understanding of the relative importance of critical pathways contaminant transport across the sediment/seawater interface in the risk, fate and management of near-shore, in-place contaminated sediments via: 1) An integrated suite of measurement techniques to characterize and quantify important transport pathways for in-place sediments, 2) A corresponding set of indices that quantify the transport phenomenon on a common dimensional scale and 3) Field scale evaluation of the effectiveness of the measurement tools and the importance of quantified transport pathways. This program consisted of two field demonstrations, the first at Paleta Creek in San Diego Bay, California, and the second at Southeast Loch and Bishop Point in Pearl Harbor, Hawaii. The detailed methods, results, and analyses for the two field studies at Paleta Creek and Bishop Point can be found in Volume I and Volume II of this report, respectively. Volume III summarizes and compares the main results of the field efforts, and critically analyzes their implications for pathway analysis and ranking as a future tool in contaminated sediment management.
